Hello,
I have some questions about audio(4) mixer device.
1. Is the "audioctl play.gain" an alias of "mixerctl inputs.dac" ?
If not, what's the difference?
2. I've almost finished the ym driver and currently the mixer device
is like this:
% mixerctl -av
inputs.dac=220,220 volume
inputs.dac.mute=off [ off on ]
inputs.midi=220,220 volume
inputs.midi.mute=off [ off on ]
inputs.cd=220,220 volume
inputs.cd.mute=off [ off on ]
inputs.line=220,220 volume
inputs.line.mute=off [ off on ]
inputs.speaker=0 volume
inputs.speaker.mute=on [ off on ]
inputs.mic=0,0 volume
inputs.mic.mute=on [ off on ]
monitor.monitor=0 volume
monitor.monitor.mute=off [ off on ]
record.record=220,220 volume
record.record.source=mic [ mic line dac cd ]
outputs.master=220,220 volume
outputs.master.mute=off [ off on ]
equalization.mode=desktop [ desktop laptop subnote hifi ]
equalization.treble=0,0 treble
equalization.bass=0,0 bass
equalization.surround=0,0 surround
power.power=powersave [ powerdown powersave nosave ]
power.power.timeout=5 timeout
Here is a question.
The following parameters are not in other drivers, and
I don't know the naming convention of mixer paremeters.
What do you think about these?
Acceptable/XXX is better/should not in mixer:)/or other ?
"equalization.mode"
sensitivity of 3D enhance
"equalization.surround"
wide stereo
Should be "equalization.wide" or something?
"power.power"
powerdown: put the chip in Global Power Down Mode (~10uA)
when unused,
powersave: put the chip in Power Save Mode (~5mA) when unused,
nosave: do not power down nor power save the chip (~100mA)
Should be "power.power.mode" or something?
"power.power.timeout"
time in sec between device close and power down/save
The diff of the driver is at this location, for your information.
The "ym at isa" stuff is not intended to commit.
